H&R AWD spring on RWD? it is ok?

jauloz · 01-26-2016, 02:54 AM

came across a set of H&R sport springs for a 328xi wagon, part number 50494-2, but I have a e92 335 RWD, will they fit on my car? (should use 50490 from H&R website)

Are they exactly the same and just part number difference?

Thanks in advance!

Diameter is different as well as the length. Additionally, they are different rate. The rears have physically identical diameter on all e9x but have different rates.
Why are you even entertaining this? Springs are cheap and does not justify experimenting with them considering the labor involved.

XI front springs need an XI top hat and there may be issues with spring height as XI shocks have less travel and the lower perch is higher.

Keep things simple, stick to nonXI springs.
